Definitions

  • the invention relates to an inductive angle sensor according to the preamble of claim 1.
  • FIG. 3 From the European patent application 0 159 191 A2 is from the in FIG. 3 shown embodiment of a position sensor such an angle sensor known.
  • the construction principle of this position or angle sensor is that angularly periodically offset from each other arranged series circuits are provided by secondary coils, each series circuit consists of one or more pairs of opposite-phase-connected coils. Due to the anti-phase connection, the output signal coupled from primary coils into a series circuit of secondary coils is (approximately) zero in each case.
  • a movable element the position of which is to be determined relative to the coil arrangement, has a "flux coupler" which is made small in comparison with the extent of the measuring path and alters the coupling between the primary coil (s) and individual secondary coils.
  • the series connection of secondary coils which contains such a influenced secondary coil, now generates a non-zero output signal.
  • Each of the series circuits of secondary coils is connected to the part of a phase shifter network, so that at the output of this network there is a signal phase shifted with respect to the signal coupled into the primary coils, which depends on the position of the movable element.
  • the evaluation of the time difference between the signal coupled into the primary coils and the output signal of the phase shifter network is used to determine the respective position of the movable element.
  • a flux coupler is in the EP 0 159 191 A2 proposed a relatively small to the measuring path magnetic element or a conductive ring (page 4, paragraph 2) proposed, the latter being described as disadvantageous, since it causes only a weak output signal.
  • a disadvantage of this angle sensor is the use of a phase shifter network, whose tolerances go into the achievable accuracy of the sensor substantially. Also, the expected from the series circuit of uninfluenced secondary coils zero signal is hardly, at least not without additional complex adjustment measures to achieve.
  • angle sensors of the type mentioned above also have for each receiving coil outgoing and return lines to the loop-shaped interconnect structures.
  • a large space requirement for each receiving coil on a circuit substrate for the receiving coil structures is necessary. Due to this high space requirement, the developer is in the Design of the layout of the circuit substrate for the conductor track structures limited.
  • inductive angle sensor thus has the rotor element, which causes the coupling between the excitation coil and the receiving coil, even a special, periodic geometric structure, so that an angular change of the rotor element relative to the stator to a change in the coupling between the excitation coil and the reception coils and thus leads directly to an evaluable periodic signal.
  • the invention has the object of providing an angle sensor of the aforementioned type, which has a stator with excitation coil and a plurality of receiving coils and a rotor element with at least one short-circuit line, so educate that it has a higher resolving power in more compact dimensions.
  • connection point is electrically connected to a receiving coil with a common summation point.
  • the connection of a receiving coil is then connected to the sum line - comparable to the star connection of a three-phase alternator with neutral point. Since the return lines of the individual receiving coils therefore do not have to be returned to the board, the number of receiving coils can thus be doubled with the same printed conductor density, whereby the resolving power of the angle sensor can be correspondingly increased.
  • stator element comprises a multilayer printed circuit board on which the excitation coil, the receiver coils and an evaluation circuit are arranged, the receiver coils forming a periodically repeating loop structure in the circumferential direction by conductor tracks arranged on different circuit board levels. This leads to a further reduction of the size of the sensor.
  • the rotor element forms a short-circuit line or has a short-circuit line which forms a periodic loop structure at least along partial regions of the rotor element in its circumferential direction.
  • This periodic loop structure is described in e.g. formed substantially meandering and similar (or even resembles) so that the geometric structure of the receiving coil.
  • the output voltages of a plurality of receiver coils can be used for position evaluation.
  • a compensatory or, particularly advantageous, ratiometric evaluation of a plurality of coil voltages manufacturing tolerances of the inductive angle sensor or even errors due to misalignments of parts of the sensor arrangement relative to one another or even larger interferences can be well compensated.
  • the support material of the rotor element but also made of plastic or a hybrid material, wherein the periodic loop structure can be realized by a metal coating or by a conductor paste.
  • the receiving coils on the stator as well as the short-circuit line of the rotor element form a periodic loop structure.
  • the contour of a conductor loop is given by the fact that it can be unambiguously described in a polar coordinate system and that the gradient of the curve described in the polar coordinate system df (r, ⁇ ) / d ⁇ is alternately positive and negative, with the part of the negative gradient curve being symmetrical is part of the curve with a positive gradient (eg triangular) and at the reversal points can also have a part with the gradient zero (eg formed as a meander, trapezoid).
  • the output signals of individual coils are electrically inverted and also used for the evaluation, while results in an even number of receiving coils by inverting a coil output signal exactly the coil output signal of another receiving coil.
  • the information content of the output signals is thus substantially increased with an odd number of receiving coils.
  • the exciter coil can be designed to be particularly simple as a conductor track guided concentrically along the circumference of the stator element. However, to realize small sensor diameters, it can also be used "behind" the receiver coils, i. be arranged in a plane parallel to the receiving coil.
  • the excitation circuit is, particularly advantageous, executable as an LC resonant circuit by utilizing the excitation coil as an inductance. Compared to a quartz oscillator so at least the cost of a quartz crystal can be saved.
  • an LC resonant circuit - as a so-called "soft" resonant circuit - reacts more flexibly and insensitive to external electromagnetic interference.
  • the evaluation circuit evaluates the conductor voltages of the receiver coils ratiometrically.
  • the evaluation circuit for example, depending on the angular range, to select the receiver coil voltages to be evaluated, respectively, so as to achieve the highest possible accuracy.
  • the excitation coil (2) consists of one or more conductor track turns on a printed circuit board, not shown. This conductor is electrically connected to a capacitor (C), so that together with the inductance of the conductor results in an LC resonant circuit (6).
  • This LC resonant circuit (6) includes an active circuit, which controls the LC circuit such that in the excitation coil (2) results in a sinusoidal voltage and current waveform.
  • the current flowing through the excitation coil (2) now generates an alternating magnetic field in the receiving coil (3), which is located within the area interspersed by the alternating magnetic field.
  • magnetic induction arise at the terminals (S1, S2, S3) of the receiving coils (3) induced voltages that are supplied to an evaluation circuit, not shown here.
  • the receiving coil system (3) of the angle sensor consists of three individual receiving coils (3 a, 3 b, 3 c), which are offset by a certain angle and preferably arranged on several levels of a multilayer printed circuit board. Since each receiving coil (3 a, 3 b, 3 c) in the circumferential direction of the stator (1) each 6 turns, formed by a meandering loop structure, one obtains a symmetrical coil arrangement, the turns of adjacent coils are offset by 20 ° from each other.
  • the rotor element belonging to the angle sensor is located without contact at a small distance from the stator element (1) and is arranged rotatable relative to this with respect to a common axis of symmetry.
  • the rotor forms at least one short-circuit line which, at least over partial regions, has a periodically repeating loop structure along the circumferential direction of the rotor element.
  • the rotor element In the simplest case, the rotor element, not shown, consists of two or more conductive segments. In the alternating magnetic field of the excitation coil (2) caused by magnetic induction eddy currents in the rotor segments, which weaken the exciting field. Due to the geometric shape of the segments of the eddy current is forced to certain tracks, which cause the magnetic field in defined segments is changed over the circumference. This uneven field change means that the induced voltages in the receiver coils (3) are dependent on the relative angle of the rotor element to the receiver coils (3). The tapped at the receiving coil (3) induction voltages thus change with the relative position of the rotor element to the receiver coils (3). The voltage curve over the angle of rotation is approximately sinusoidal.
  • the receiver coil (3) consists of a plurality of offset by a certain angle tracks (3 a, 3 b, 3 c), are available for the evaluation of several voltages whose signal amplitudes are phase-shifted by the angle to each other. To generate the angle information, these voltages are set in relation to one another in an evaluation circuit. Thereby The generated angular position is independent of the absolute induced voltages and thus independent of various manufacturing tolerances. Also coupled interference are largely suppressed by this ratio formation.
  • the short-circuit line of the rotor element not shown, have the same loop structure or at least one loop structure with the same angular periodicity as one of the receiver coils (3). Further, suppose that at a given time, the loop structure of the rotor element would be exactly parallel to the loop structure of the receiver coil (3 a) drawn in thick outline and would be rotated further from this position by 60 °.
  • the voltage profiles (U1, U2, U3) resulting here at the coil terminals (S1, S2, S3) are in the FIG. 4 shown.
  • the loop of the rotor element In the initial position, the loop of the rotor element is parallel to the receiving coil (3 a). Since the loop represents a short-circuit line, the field is thus greatly weakened and in the receiving coil (3 a) induced voltage (U1) is minimal. Since the receiving coils (3 b, 3 c) are only partially covered here by the loop of the rotor element, a voltage (U 2, U 3) of medium magnitude arises in each case, the sign of which depends on the direction in which the part covered by the short-circuit line the Empfangsspulenwindung runs.
  • the output signal of the receiving coil (3) about the rotation angle changes approximately sinusoidally, in accordance with the angular periodicity of the individual receiving coils (3). Larger angles than here, for example, 60 ° can be easily detected by counting the periodic repetitions of the output signals.
  • FIG. 5 is under a) the structure of the three receiving coils (3 a, 3 b, 3 c) (from the FIG. 3 ) with their connections (S1, S2, S3) have been transferred to a linear route. It can be seen that the track density for the formation of the three receiving coils is quite high here.
  • the same information content from the signals of the three receiving coils can also be used with a track arrangement according to the FIG. 5 b) be achieved.
  • the conductor density is here only half as large as in the FIG. 5 a) , which is achieved in that at each receiving coil "the return line is saved" and in each case one terminal of each receiving coil is guided to a common summation point (7).
  • This summation point (7) is comparable to the neutral point of an alternator.
  • the potential of the summation point is zero in the ideal case and is therefore not supplied by the evaluation circuit or at best for the correction of disturbing influences.
  • the "actual" receiver coils now result by selecting two of the "forward lines", that is, the receiver coil output signals now arise between the terminals S1 and S2 or S2 and S3 or S3 and S1, the course of these signals qualitatively the in the FIG. 4 represented corresponds.
  • the particular advantage of this embodiment compared to that in the FIG. 5 a) is that with the same interconnect density a twice as high number of receiving coils can be applied to a circuit board, whereby the resolution of the inductive angle sensor according to the invention can be doubled accordingly.
  • FIG. 1 shows the stator 1.
  • the excitation coil (2) On a multi-layer printed circuit board (8), the excitation coil (2), the receiving coil (3) and an evaluation circuit (9) are arranged.
  • the circuit of the evaluation circuit (9) further includes the oscillator for the excitation coil (2), designed as an LC resonant circuit (6), wherein the inductance is formed by the exciter coil (2).
  • the evaluation circuit (9) has in addition to the terminals (10, 11) for connecting the excitation coil (2) and the receiving coil (3) nor voltage supply terminals (+ UB, ground) and a Meßsignalausgang (output), the z. B. are guided to a connector, not shown.
  • the arrangement of the excitation coil (2) and the receiving coil (3) is approximately circular, wherein in the peripheral region of the arrangement, the exciter coil (2) is formed of a plurality of concentrically guided conductor turns.
  • the receiving coils (3) will form a periodically repeating loop structure (eg triangular or meander-shaped) in the circumferential direction by conductor tracks arranged on different circuit board levels.
  • the angular periodicity of each of these loop structures is 30 °.
  • the evaluation circuit (9) rectifies the alternating voltages induced in the receiver coils (3), amplifies them and sets the output voltages of two receiver coils relative to one another for position evaluation (ratiometric evaluation).
  • the apparently confusing arrangement of the receiver coils (3) results in the FIG. 1 only in that all arranged on different levels of the circuit board (8) receiving coils are projected into a common plane of the drawing.
  • the dot-shaped printed conductor endings respectively indicate plated-through holes (12) between the individual levels of the printed circuit board (8).
  • FIG. 2 In the FIG. 2 is a possible interconnect structure of an associated rotor element (4) shown. On a circular support (13), z. As a circuit board, a short-circuit line (5) in the form of a circumferentially of the carrier (13) is applied periodically repeating loop structure.
  • the angular periodicity of this loop structure is 30 ° and is therefore the same as the angular periodicity of the individual receiving coil structures. This match is not mandatory, but expedient for the sake of the simplest possible to carry out signal evaluation.
  • the entire short-circuit line (5) is formed here by a single conductor track, which is in addition to the characteristic meander shape also several times spirally interleaved.
  • the beginning and end points of the short-circuit line (5) via two plated-through holes (12), z. B. on the back of the circuit board, electrically connected.
  • an identically structured short-circuit line can be provided on the back of the track.
